Here's my view. If it's possible to give people the ability to have 
their e-mail addresses obfuscated, I would recommend making that a 
non-default option. I think spam, viruses and worms are a menace and 
those responsible for them should be dealt with harshly. I also think 
the appropriate place to systematically deal with them is not at the 
mailing-list/newsgroup level. I like using e-mail to communicate and 
don't want my own e-mail address obfuscated. I have a pretty good junk 
filter that is capable of learning about new junk and I take great 
satisfaction in looking at my junk folder before I delete every junk 
e-mail without reading them. But I do think people should be given a 
choice on the matter.
